The Otway Basin is a major sedimentary onshore and offshore basin for oil and gas. The basin’s onshore section covers an area of 155,000 km2 between Geelong and Lucindale in South Australia.
Since the 1970s, exploration in the basin has resulted in numerous onshore and offshore gas discoveries. All of the commercially viable gas discoveries within the Victorian section of the basin have been in the Peterborough and Port Campbell areas.
Currently, natural gas is being produced from the basin’s offshore fields including Halladale, Blackwatch and Speculant, and stored in onshore underground depleted gas fields.
